Polarization Maintaining Fused WDM(PMWDM)

LightComm uses unique fusing technique and polarization maintaining fiber to build the polarization maintaining fused WDM (PMWDM).The wavelength could be selected according to customer’s request.  It features low excess loss, small size, high polarization extinction ratio and high isolation. PMWDM is widely used for optical sensors, fiber gyro, optical amplifier.
